With the improved CMOS low jitter design, Abracon ASELJ series offers low RMS phase

jitter capable of reaching a phase noise floor of -171 dBc/Hz. This series feature three

supply voltage options of 1.8V, 2.5V, and 3.3V. In addition, the ASELJ series comes in a

frequency range of 0.625 MHz to 50 MHz with an overall frequency stability of ±25 ppm

over an operating temperature range of -40

℃to85℃.
